| titleOfInvention | Polymeric esters and wire enamels containing the same |
| abstract | Polyesters are made by reacting together (a) 4,41-benzophenone dicarboxylic acid or an ester-forming derivative thereof, alone or in admixture with tere- and/or iso-phthalic acid or ester-forming derivatives thereof and (b) tris-(2-hydroxyethyl)-isocyanurate or a mixture thereof with another polyhydric alcohol. Specified other polyhydric alcohol are ethylene glycol, 1:4-butanediol, 1:5-pentanediol, butene-2-diol-1:4, butyne-2-diol-1:4, 2:2:4:4 - tetramethyl - 1:3 - cyclobutanediol, 1:4-cyclohexanedimethanol, hydroquinone di-(beta-hydroxyethyl) ether, glycerine, pentaerythritol, 1:1:1 - trimethylolpropane, 1:1:1 - trimethylolmethane, sorbitol, mannitol and dipentaerythritol. Polyesterification is preferably effected by heating the reactants together in the presence of an organic solvent at 80 DEG C. to replace temperature. Wire enamels are made by dissolving the resins in an organic solvent, e.g. the cresols, aromatic naphthas, xylenes, aliphatic hydrocarbon or N-methyl pyrrolidone and possibly adding (1) a polyisocyanate or a blocked polyisocyanate, (2) a linoleate, octoate, resinate or naphthanate of Zn, Pb, Cu, Cd, Mn or Co, (3) a tetra-alkyl titanate, (4) an alkane dicarboxylic acid, or (5) a butylated melamine-formaldehyde resin. The resin may also be used in the manufacture of moulded products of the impregnation of cloth, paper and asbestos. In example, resins are made by reacting 4,41-dimethyl benzophenone dicarboxylate or a mixture thereof with dimethyl terephthalate with tris(2-hydroxyethyl) isocyanurate or a mixture thereof with ethylene glycol. Reference has been directed by the Comptroller to Specification 961,624. |
